chomp
Removes the trailing record separator (default: newline) from each argument. Returns the total number of characters removed.
Respects $/ (input record separator). When $/ is undef (slurp
mode), chomp is a no-op. When $/ is "" (paragraph mode), removes
all trailing newlines. Handles CRLF line endings — \r\n counts as
2 characters removed.
